Abstract
The utility model relates to a connecting sleeve for a steel drill rod, and belongs to the technical field of steel drill rods of rock drills. The connecting sleeve is a sleeve body (1) in structure; two conical inner holes (2 and 3) symmetrically arranged at the same coaxial core are formed in the sleeve body; the conical heads of the two conical inner holes (2 and 3) are communicated; and spiral wales (4) are formed on the outer surface of the sleeve body (1). Broken steel drill rods can be reused with the connecting sleeve, the utilization rate of drill rods is maximized, material is saved, and use cost is reduced and therefore, the connecting sleeve has certain economic and social benefits.
Description
Technical field
The utility model belongs to hammer drill drill rod drill steel technology, is specially a kind of drill rod drill steel adapter sleeve.
Background technology
At industrial departments such as mining, water conservancy, railway and building materials, hammer drill is the most frequently used engineering equipment, and along with the constantly bringing forth new ideas and popularizing of heavy efficient hydraulic hammer drill, its matching used drill steel will directly influence the efficient and the rock drilling cost of hammer drill application life.Though drill steel all has strict demand from many technologies such as selection, system pricker and heat treatments, but be prone to weak link, the drill rod drill steel phenomenon that fractures is often arranged, and prior art is to adopt a threaded cover to interconnect to the connection of disconnected drill rod drill steel, its shortcoming: the one, because also needing to be processed into screw thread, disconnected drill rod drill steel could be complementary with adapter sleeve, cause the outside diameter of drill steel to dwindle, be easy to fracture, reduced operating efficiency thereby cause drill steel to disconnect; The 2nd, processed complex trouble, time-consuming, use cost height.
The utility model content
The purpose of this utility model provides a kind of drill rod drill steel utilization rate height, is connected firmly convenient disassembly, the simple and low drill rod drill steel adapter sleeve of cost of processing.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of drill rod drill steel adapter sleeve, comprise a sleeve body, two cone-shaped inner holes are arranged in the sleeve body, two cone-shaped inner holes are that concentric is symmetrical arranged, the conehead of two cone-shaped inner holes communicates, two cone-shaped inner holes are rounded or hexagon in the end of sleeve body, and the external surface of above-mentioned sleeve body has the spiral burr.
Characteristics of the present utility model are the disconnected drill rod drill steel recyclings that can will scrap, make the utilization rate of drill steel can arrive maximization, have saved material, have reduced use cost.The utility model also can will have drill rod drill steel lengthening now, as: 2 meters on the longest existing drill rod, boring needs 3 meters deeply, as long as connect 1 meter short pricker; Antagonism place limitation function, as, 2 meters drill rods of the place the longest use of restriction, and 3.5 meters of desirable drilling depths, as long as bored with 2 meters drill rods earlier, 1.5 meters drill rods of adjunction get final product then.Therefore the utility model is skillfully constructed, and is reasonable in design, the location of can contracting certainly, convenient disassembly, saving of work and time; The outer hexagon of adapter sleeve or circular drill rod drill steel match, and self-locking is not press-offed, and does not produce idle running, and the spiral burr design of sleeve body external surface can be assisted deslagging, make the rock drilling operating efficiency improve 1-2 doubly, have the certain economic social benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1;
Fig. 3 is a user mode schematic diagram of the present utility model.
Among the figure: 1 sleeve body; 2 cone-shaped inner holes; 3 cone-shaped inner holes; 4 spiral burrs; 5 drill rod drill steels; 6 drill rod drill steels.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1
See Fig. 1 and Fig. 2, a kind of drill rod drill steel adapter sleeve is a sleeve body 1, and cone-shaped inner hole 2 and cone-shaped inner hole 3 are arranged in the sleeve body, and cone-shaped inner hole 2 and cone-shaped inner hole 3 are for concentric is symmetrical arranged, and the conehead of cone-shaped inner hole 2 and cone-shaped inner hole 3 communicates; Cone-shaped inner hole 2 and cone-shaped inner hole 3 are rounded in the end of sleeve body 1.The external surface of above-mentioned sleeve body 1 has spiral burr 4 to be used for auxiliary deslagging.
During use, principle according to Morse's taper, at drill rod drill steel adapter sleeve with drill rod drill steel 5 with after drill rod drill steel 6 is connected, pyramidal structure can be determined the center and produce certain power that contracts certainly, do not cause drill rod drill steel 5 and drill rod drill steel 6 to come off, only need when not using that adapter sleeve is knocked several drill rod drill steels 5 down and can break away from, use very convenient with drill rod drill steel 6.
A kind of drill rod drill steel adapter sleeve is a sleeve body 1, and cone-shaped inner hole 2 and cone-shaped inner hole 3 are arranged in the sleeve body, and cone-shaped inner hole 2 and cone-shaped inner hole 3 are for concentric is symmetrical arranged, and the conehead of cone-shaped inner hole 2 and cone-shaped inner hole 3 communicates; Cone-shaped inner hole 2 and cone-shaped inner hole 3 are hexagon in the end of sleeve body 1.The external surface of above-mentioned sleeve body 1 has spiral burr 4 to be used for auxiliary deslagging.
Claims (3)
1, a kind of drill rod drill steel adapter sleeve is a sleeve body (1), it is characterized in that: two cone-shaped inner holes (2,3) are arranged in the sleeve body, and two cone-shaped inner holes (2,3) are for concentric is symmetrical arranged, and the conehead of two cone-shaped inner holes (2,3) communicates; The external surface of above-mentioned sleeve body (1) has spiral burr (4).
2, drill rod drill steel adapter sleeve according to claim 1 is characterized in that: described two cone-shaped inner holes (2,3) are rounded in the end of sleeve body (1).
3, drill rod drill steel adapter sleeve according to claim 1 is characterized in that: described two cone-shaped inner holes (2,3) are hexagon in the end of sleeve body (1).
